Abstract

A system (1) for forming products from an elastomeric material such as rubber or the like comprises a buffer unit or feed chamber (4) having a body (10) comprising two opposing surfaces (13, 14), which receives said material from a charging member or tank, and presents at least one nozzle (30) projecting from at least one of said surfaces (13, 14), to enable said material in plastic form to be transferred to a platen (5) disposed in front of said at least one surface and presenting at least one impression corresponding to the product to be obtained, presser means being provided to bring said buffer unit (4) into contact with said platen (5) and enable said nozzle (30) to engage, within the platen (5), a surface seat (5H) connected to said impression such as to enable elastomeric material to be transferred into this latter and obtain the final product after solidification. The nozzle (30) is movable relative to that surface (13, 14) of the buffer unit (4) from which it projects.
